The cell phone companies can contract with google to do whatever they want. It should be up to the businesses to negotiate the kind of contracts they want to see. But if they can agree on business terms, there is no reason that the FCC should intervene. Business is business.
Even though right now mobile service providers are going through a pretty major price war, in other ways the options that exist for mobile customers are limited, and the market could use some shaking up. Here enter Google Wireless. The possibilities for innovation in mobile service are particularly interesting given that Google is also a major manufacturer of smart phones as well as the operating system that they run on, not to mention their many very useful free web services. Integration among all these elements could be a major boon for mobile customers.
Google should not be doing anything to alienate itself from the 2 biggest cell phone carriers in our country if you ask me. A move like this may make Verizon and AT&T look to do a similiar link up with another internet company and the outcome may possibly end google.
Google, already a monolith in the tech world, seems to be getting to needy and greedy. It is not reasonable for Google to expect to use Sprint and T-Mobile services at reduced rates so they can provide services that they will profit from. This is like demanding you get a cut of your neighbor's house sale because you once mowed their lawn.
